Service
Your retailer knows your vehicle best and wants you to
be happy with
it. We hope you‘ll go to your retailer for
all your service needs. You’ll get genuine GM parts and
GM-trained and supported service people.
We hope you’ll want
to keep your GM vehicle all GM.
Genuine
GM parts have one of these marks:

Doing Your Own Service Work
If you want to do some of your own service work, you’ll
want to use the proper GM Service Manual.
It tells you
much more about how to service your vehicle than this
manual can.
To order the proper service manual, see
.‘Service and Owner Publications”
in the Index.
Your vehicle has an air bag system. Before attempting t.o
do your own service work, see “Servicing Your
Air
Bag-Equipped Vehicle” in the Index.
You should keep a record
with all parts receipts and list
the mileage and
the date of any service work you
perform. See “Maintenance Record” in the Index.

You can be injured and your vehicle could be
damaged
if you try to do service work on a
vehicle without knowing enough about it.
0 Be sure you have sufficient knowledge,
experience, the proper replacement parts
and tools before you attempt any vehicle
maintenance task.
0 Be sure to use the proper nuts, bolts and
other fasteners. “English” and “metric”
fasteners can be easily confused.
If you use
the wrong fasteners, parts can later break
or fall off. You could be hurt.
Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your vehicle can
affect the airflow around
it. This may cause wind noise
and affect windshield washer performance. Check with
your retailer before adding equipment to the outside
of
your vehicle.
Fuel
Use regular unleaded gasoline rated at 87 octane or
higher.
At a minimum, it should meet specifications
ASTM
D48 14 in the United States and CGSB 3.5-M93
in Canada. Improved gasoline specifications have been
developed by the American Automobile Manufacturers
Association (AAMA) for better vehicle performance
and engine protection. Gasolines meeting the AAMA
specification could provide improved driveability and
emission control system protection compared to
other gasolines.
ProCarManuals.com

Be sure the posted octane is at least 87. If the octane is
less than 87, you may get a heavy knocking noise when
you drive.
If it’s bad enough, it can damage your engine.
If you’re using fuel rated at 87 octane or higher and you
hear heavy knocking, your engine needs service. But
don’t worry
if you hear a little pinging noise when
you’re accelerating or driving up
a hill. That’s normal,
and
you don’t have to buy a higher octane fuel to get rid
of pinging. It’s the heavy, constant knock that means
you have a problem.
If your vehicle is certified to meet California Emission
Standards (indicated on the underhood emission control
label), it is designed to operate on fuels that meet
California specifications.
If such fuels are not available
in states adopting California emissions standards, your
vehicle
will operate satisfactorily on fuels meeting
federal specifications, but emission control system
performance may be affected. The malfunction indicator lamp
on your instrument
panel may turn on and/or your vehicle may fail a
smog-check test.
If this occurs, return to your authorized
GM retailer for diagnosis to determine the cause
of
failure. In the event it is determined that the cause of the
condition
is the type of fuels used, repairs may not be
covered by your warranty.
Some gasolines that are not reformulated for
low
emissions contain an octane-enhancing additive called
tnethylcyclopentadienyl manganese tricarbonyl (MMT);
ask your service station operator whether or not
his fuel
contains MMT. General Motors does not recommend the
use of such gasolines.
If fuels containing MMT are used,
spark plug life may be reduced and your emission
control system performance may be affected. The
malfunction indicator lamp on your instrument panel
may turn on.
If this occurs, return to your authorized
GM retailer for service.

To provide cleaner air, all gasolines in the United States
are now required to contain additives that
will help
prevent deposits from forming
in your engine and fuel
system, allowing your emission control system to
function properly. Therefore, you should
not have to add
anything
to the fuel. In addition, gasolines containing
oxygenates, such
as ethers and ethanol, and
reformulated gasolines may be available in your area to
help clean the air. General Motors recommends that you
use these gasolines
if they comply with the
specifications described earlier.
NOTICE:
Your vehicle was not designed for fuel that
contains methanol. Don’t use it. It can corrode
metal parts in your fuel system and also damage
plastic and rubber parts. That damage wouldn’t
be covered under your warranty.
Fuels in Foreign Countries
If you plan on driving in another country outside the
United States or Canada, the proper fuel may be hard to
find. Never use leaded gasoline or any other fuel not
recommended in the previous text on fuel. Costly repairs
caused by use of improper
fuel wouldn’t be covered by
your wa1-ranty.
To check on fuel availability, ask an auto club, or
contact
a major oil company that does business in the
country where you’ll be driving.
You can also write LIS at the following address for
advice.
Just tell us where you’re going and give your
Vehicle Identification Number
(VIN).

Filling Your Tank
The fuel cap is behind a hinged door on the driver’s side
of your vehicle.
Gasoline vapor is highly flammable. It burns
violently, and that can cause very bad injuries.
Don’t smoke if you’re near gasoline or refueling
your vehicle. Keep sparks, flames and smoking
materials away from gasoline.

While refueling, hang the cap by the tether from the
hook
on the filler door.
To remove the cap, turn it slowly to the left
(counterclockwise). The cap has a spring
in it; if you let
L go of the cap too soon, it will spring back to the right.
Y If you get gasoline on yourself and then
something ignites it, you could be badly burned.
Gasoline can spray out on you
if you open the
fuel filler cap too quickly. This spray can happen
if‘ your tank is nearly full, and is more likely in
hot weather. Open the fuel filler cap slowly and
wait for any “hiss” noise to stop. Then unscrew
the cap
all the wav.
Be careful not to spill gasoline. Clean gasoline from
painted surfaces
as soon as possible. See “Cleaning the
Outside
of Your Vehicle” in the Index. When
you put the
cap back on, turn it to the right
(clockwise)
until you hear a clicking sound. Make sure
you
filly install the cap. The diagnostic system can
determine
if the fuel cap has been left off or improperly
installed.
This would allow fuel to evaporate into the
atmosphere. See “Malfunction Indicator Lamp” in the
Index.
NOTICE:
If you need a new cap, be sure to get the right
type. Your retailer can get one for you. If you get
the wrong type, it may not fit properly. This may
cause your malfunction indicator lamp to light
and your fuel tank and emissions system may be
damaged. See “Malfunction Indicator Lamp” in
the Index.

Filling a Portable Fuel Container Checking Things
Under the Hood
Never fill a portable fuel container while it is in
your vehicle. Static electricity discharge from the
container can ignite the gasoline vapor. You can
be badly burned and your vehicle damaged if this
occurs. To help avoid injury to you and others:
Dispense gasoline only into approved
containers.
Do not fill a container while it is inside a
vehicle, in a vehicle’s trunk, pickup bed or
on any surface other than the ground.
inside of the fill opening before operating
the nozzle. Contact should be maintained
until the filling
is complete.
Bring the fill nozzle in contact with the
Don’t smoke while pumping gasoline. Things that burn can

start
a fire. These include liquids like gasoline,
oil, coolant, brake fluid, windshield washer and
other fluids, and plastic or rubber. You or others
could be burned. Be careful not to drop or spill
things that
will burn onto a hot engine.
